Seamus has hit at this before; been meaning to respond because I think it displays a fundamental misunderstanding of Tumblr. Namely, that it is designed to be consumed/experienced primarily on the public-facing side.
In fact, while you can easily read this Tumblr like any other blog, and even, like most other blogs, make a comment down below, the real interaction is designed to take place among Tumblr users within the dashboard. In the case of Newsweek, posts usually averaged between 20 and 200 notes (that is, ‘likes’ and ‘reblogs’ of a particular post); some were as high as 3,000 notes.
That’s a significant level of engagement, and one that, if anything, is actually underrated.
We feel a little like the kid on the playground whose dad just stood up for us against the neighborhood bully.
It’s exactly this potential for engagement that Mark refers to that excites us most about Tumblr. Reading us from the front end is fine and dandy, but you’re selling your experience short. We want you to talk to us, share with us, argue with us. Seriously, we love it.
